How will the public opinions put forward during the patent examination affect the applicants?

It usually doesn't matter. The examiner will refer to the opinions of the sponsor in the review process and will not adopt them unconditionally. In the notice, he won't write XXX and put forward public opinions. The applicant usually doesn't know who put forward it. Of course, if the proposer has an interest in the case under review, the proposer will still benefit if the case is finally rejected.
